16、This Technical Specification comprises three shoe size conversion tables covering the major shoe sizing systems (Mondopoint, European and United Kingdom, as well as China, Japan and United States). The tables are based on measurement of foot length, this being the logical starting point for any shoe
17、 size marking system. The tables contain the following information: Table 1 Adults technical shoe size conversion; Table 2 Adults recommended shoe size marking (simplified); Table 3 Childrens size conversion. Explanatory notes are given in Clause 3. NOTE It is acknowledged that, due to the different
18、 ways in which each system has been developed and interpreted over many years without being formalized into any national or International Standards (other than ISO 9407), there is no exact solution to the problem of accurate shoe size conversions. Tables 1 and 2 offer a good compromise solution whic
19、h will, if adopted, benefit the consumer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of th
20、e referenced document (including any amendments) applies. ISO 9407, Shoe sizes Mondopoint system of sizing and marking ISO/TS 19408, Footwear Sizing Vocabulary and terminology 3 Explanatory notes 3.1 General There are three main sizing systems (Mondopoint, European and UK). As there are fundamental
21、differences between them, they have been aligned to a common denominator: foot length. Foot length is deemed to be the key reference point when fitting footwear. Customers foot length can be readily measured and shoes marked with a designation that indicates the appropriate shoe size that will accom
22、modate their foot length. Customers expect to buy the same size of footwear irrespective of the footwear type or style. NOTE To check that size marking is correct requires a practical fit assessment of footwear whereby subjects having appropriate foot lengths for the marked size don the footwear and
23、 the available toe allowance is assessed for satisfactory fit. Some allowance for foot width may also have to be made. This Technical Specification, however, does not attempt to assess the overall fitting properties of footwear i.e. it does not cover width, volume, toe depth, etc. 3.2 Table 1 Adults
24、 technical shoe size conversion a) The Mondopoint system is defined in ISO 9407 and is based on foot length. The size grading intervals used with Mondopoint are given in DIN 66074-2:1975 as 5 mm (Range 1) or 7,5 mm (Range 2), both starting at zero. In practice, 10 mm intervals are commonly referred
25、to as whole sizes and 5 mm intervals as half sizes. Intervals of 7,5 mm are used mainly for specialized footwear. China and Japan TECHNICAL SPECIFICATION ISO/TS 19407:2015(E) ISO 2015 All rights reserved 1 PD ISO/TS 19407:2015 ISO/TS 19407:2015(E) use the Mondopoint system for length designation; Ja
26、pan sometimes expresses size in centimetres rather than millimetres. NOTE 1 Some footwear is marked with a CM or CMS size marking; this usually indicates a Mondopoint size in centimetres rather than millimetres though sometimes appears to indicate last length. b) The European system (EUR) (previousl
27、y known as Paris Points, French or Continental) is based on a size grading interval of 6,67 mm, starting at zero. This system may be interpreted as being based on last length or foot length depending on the country of origin, resulting in differences in shoe size markings (see Note 2). c) The United
28、 Kingdom system (UK) is based on a size grading interval of 8,47 mm, starting at 101,6 mm (4 inches or equivalent to 12 size grading intervals). The first 13 sizes are referred to as childrens sizes; the scale then re-starts at size 1 for larger sizes. This system was originally developed with regar
29、d to shoe or last length but subsequently redefined in terms of foot length. d) The United States system (US) is based on a size grading interval of 8,47 mm, starting at 99,5 mm (3 inches). The first 13 sizes are referred to as childrens sizes; the scale then re-starts at size 1 for larger sizes. In
30、 practice, however, the US system corresponds directly to the UK system but with the addition of an arbitrary off-set of one size difference for mens footwear and usually two sizes difference for womens footwear. Table 1 gives precise conversion data utilizing mathematical relationships between the
31、different scales based on an understanding of how the systems are generally implemented in practice. A UK adult size is calculated from the foot length as: l where l f is foot length. 25 12 sizes plus 13 children sizes, and 12 sizes 101,6 mm or 4 inches. An EUR size is calculated from foot length as
32、: l In both cases the difference between foot length and shoe or last length is taken as being empirically equivalent to two sizes (two UK sizes or two EUR sizes respectively). NOTE 2 An alternative approach to the European system, which is in use but not adopted here, is based on a 5 % difference b
33、etween foot length and last length as opposed to a two grade interval difference. The two approaches give very similar size conversions to the Mondopoint and UK systems for sizes 38 to 46, but differ by approximately half a European size at the smallest and largest sizes. Column 1 gives the exact fo
34、ot length values for EUR and UK whole and half sizes, plus Mondopoint standard values (Ranges 1 and 2) where no EUR or UK foot length value lies within 0,5 mm. Columns 6 and 7 are for information only and indicate the approximate range of effective last lengths that might be associated with each foo
35、t length. The actual last length will usually be greater than the effective last length due to toe shape/fashion design (see ISO/TS 19408). NOTE 3 Some customers might be surprised to see the EUR/UK size conversions given here and believe that the EUR size markings should be increased by half a size
36、 against the UK scale. For example, Table 2 shows 4 UK 36,5 EUR and 8 UK 41,5 EUR, while footwear is often labelled 4 UK/37 EUR and 8 UK/42 EUR. However, Tables 1 and 2 are considered more technically correct.2 ISO 2015 All rights reserved PD ISO/TS 19407:2015 ISO/TS 19407:2015(E) 3.3 T able 2 A dul
37、ts r ec ommended shoe size mar king (simplified) To simplify Table 1 for the practical requirement of shoe labelling, while retaining the highest degree of accuracy with respect to foot length, requires a knowledge of which system was used to manufacture and grade the footwear. Table 2 therefore giv
38、es the most accurate size conversions possible based on each of the three main sizing systems (Mondopoint, EUR or UK). It should be noted however, that even in this table, approximate size conversions have had to be used because the fundamental difference in size grading interval means that exact si
39、ze conversions cannot be given to whole or half sizes. It is suggested that shoe labels might also reflect this information, for example, by use of bold font to indicate the size grading system used to manufacture the footwear, with the converted sizes following in plain font: Womens Mondo EUR UK US
40、 240 38 5,5 7, 5 Mens EUR Mondo UK US 41 260 7, 5 8,5 NOTE As a general rule, it is desirable to mark a shoe size down slightly as oppose to up so that it will encourage wearers to try a slightly generous fitting shoe rather than slightly tight fitting shoe. This will tend to benefit foot comfort an
41、d health. However, in practice, the wearer will chose whichever size suits their personal preference. 3.4 Table 3 Childrens recommended shoe size marking Shoe size and typical effective last length are based on foot length plus a toe allowance of 8 % of foot length. The US system is based on the UK
42、system but with the addition of an arbitrary offset of usually half a size difference for childrens footwear.
